| PURPOSE: To make surplus thickness unnecessary, enable recovery of a pile driving head from an interior of a pipe without requiring a special fixture, enables to inspect the bottom end of the driven pipe at any time as required during pile-driving work and markedly reduce noises caused by driving impact by designing the thickness of the pipe separately from strength against driving to make surplus energy unnecessary. CONSTITUTION: A pile driving head 2, disposed at a bottom end within a pipe 1 for driving a foundation pile, is driven by a hydraulic or electromagnetic hammer 3 to drive the pipe into the ground. The bottom end of the pipe is provided with a support face 4 extending in an inner face so that a pile driving head, capable of being inserted and drawn from a top end of the pipe is seated on the support face. The head is moored to the bottom end of the hammer, in such a manner as to be movable in vertical directions and is provided with a leading penetration sharp head part 6 which protrude from the bottom end of the pipe.

| PURPOSE:To generate a striking force with short cycles and lesser vertical vibration amplitudes by a method in which an excavating tooth is projectionally provided at the downside of an attachment to be fitted with the lower end of a pile and an elastomer is set on the upside of the bottom plate. CONSTITUTION:In an attachment B for driving a pile, an H-shaped hollow cap 1 slightly larger than a pile A is formed by matching the shape of the lower end of various kinds of piles, e.g., H-shaped steel pile A. Also, an excavating tooth 2 of a triangle form is projectionally formed on the downside of the hollow cap 1, and an elastic material 3, e.g., plate spring, etc., is set on the inner bottom plate of the hollow cap 1. The attachment B is fitted into the lower end portion of the pile A and the pile is driven vibrationally, whereupon the vibration and load of the pile A are transmitted to the attachment B and a striking force is generated to the ground by the attachment B itself. | ||||||

| PURPOSE:To drive a pile with good efficiency by attaching an inside covering plate and an outside covering plate, each having given thickness and width, to the inner and outer wall faces of the tip portion of a prefabricated pile. CONSTITUTION:An outside covering steel plate 2 having a given thickness and a given width is attached to the outer wall face 1a of the tip portion of a steel tubular pile 1. Also, an inside covering steel plate 3 having a given thickness and a given width is attached to the inner wall face 1b of the tip portion of the pile 1. Frictional resistance to be produced in driving the pile 1 acts only on the plates 2 and 3 of the pile 1, but scarcely on the other inner and outer wall faces, and therefore, the pile 1 can be driven with good efficiency. | ||||||

| PURPOSE:To simplify the attaching or detaching operation of a friction cutter for a pile by fitting and screwing the inside of the upper end of the friction cutter into a reinforcing band provided to the periphery of the tip of a pile. CONSTITUTION:A friction cutter 1 is fitted into a seat plate 5 fixed to the tip of a pile 4, its fitting piece 2 is contacted with the seat plate 5, and under the condition that the threaded hole 6 of the seat plate 5 is matched with the threaded hole 3 of the fitting piece 2, the inside of the upper end of the friction cutter 1 is fitted into a reinforcing band 7 provided to the pile 4. A screw tool 8, e.g., bolt, etc., is screwed into the threaded holes 3 and 6 to attach the friction cutter 1 to the pile 4. | ||||||

| PURPOSE:To prevent the disturbance of the ground at the tip of a pile by a method in which a pile is laid by turning an auger screw, a coupler, and a tip- expanded shoe, and while the tip-expanded shoe is fixed at the lower end of the pile, the auger screw and the coupler are recovered. CONSTITUTION:The pile coupling hook metal 5 of a tip-expanded shoe B is coupled with a tipe-expanded shoe coupling metal 14 at the lower end of a pile A, whereby the shoe B is rotatably coupled with the pile A. A coupler C is connected to the tip of an auger screw 17 inserted into the hollow of the pile A, and the projection 18b of the coupler C is fitted into the window hole 11 of the tip-expanded shoe B for fixing the coupler C to the shoe B. The shoe B is turned by means of the auger screw 17, the pile A is buried to a given depth, and then the auger screw and the coupler C are recovered and the pile A with the shoe B on its tip end is buried. | ||||||

| PURPOSE:To prevent the entrance of muddy soil and sand into an excavation hole and to improve a working efficiency, by a method wherein a mortar releasing port is formed in an excavation forward end cone, and in the case of a soft ground, mortar can be implanted in a manner to embed the forward end cone in a ground. CONSTITUTION:An excavation forward end cone 20 is constituted such that a plural number of right-angled triangular plates 24 is located in a radial manner. A flange 26 is mounted on the short side of the triangular plate 24, a screwform or rodform excavating cutter 25' is securely attached to the oblique side of the triangular plate 24, and a mortar releasing port 53 is provided. A ground is excavated through turning of a cylinder 33 having a screw vane 30 and a shaft 19 for spinning the forward end cone 20. Mortar is then implanted into a hollow pipe 10, a piston 7 is depressed, and the valve at the forward end cone is opened to place mortar, working as a consolidating material, into a ground through the mortar releasing port 53. Then, the forward end cone 20 is raised, and after a pile is driven, the screw vane 30 is removed. | ||||||
